The unnamed sources said Taliban leaders killed in the Sunday night attack included Eida Khan, wanted for cross-border attacks on U.S. soldiers in Afghanistan, and Wahweed Ullah, who allegedly worked with al-Qaida in the region, The New York Times reported.

The newspaper said the drone fired missiles Sunday night at a compound in the village of Manduta, which is near Wana, the capital of South Waziristan, about 20 miles from the border with Afghanistan.

The Pakistani official said Khan and Ullah worked with the Jalaluddin Haqqani, an Islamic militant network based in South Waziristan. The Times said the attack was the 19th known strike in Pakistan's remote tribal regions by a remotely piloted Predator aircraft since August.
